fix(onboard): select the provider a requested serving profile needs

[yanyunl1991]

Summary

onboard --profile validated the requested serving profile and recorded its provenance, but never selected a provider. Onboarding therefore fell through to the interactive provider menu with the profile unapplied. The provider is now derived from the profile's backend and exported for the run alongside the preset.

Closes #9313.

Reproduction

Environment

• Test machine: our DGX Spark aarch64 test host with a GB10 GPU, matching the reporter's platform
• Ubuntu 24.04, Node.js 22.22.2, OpenShell CLI 0.0.101
• NemoClaw main at 8cdc3c41e

nemoclaw profiles list
env | grep '^NEMOCLAW_'

nemoclaw onboard --profile vllm.dgx-spark-gb10.single.muse-glimmer-30b-nvfp4-w4a4 \
  --name muse-prof-9313 --fresh --yes --yes-i-accept-third-party-software < /dev/null

Before this change

[3/8] Configuring inference provider
──────────────────────────────────────────────────
Detected local inference options: vLLM, Ollama

Select your inference provider:
  1) NVIDIA Endpoints
  ...
  14) Local llama.cpp

Choose [1]:   Installation cancelled

The requested profile was absent from the menu, and the provenance block did not print.

After this change

[3/8] Configuring inference provider
──────────────────────────────────────────────────
[non-interactive] Provider: install-vllm

vLLM (DGX Spark):
  Image: vllm/vllm-openai@sha256:677afd5bf3b4bb9881f91e107af7098f8410726b4c05b25cb4a815900b398204
  Model: Inferact/Muse-Glimmer-30B-NVFP4-W4A4

The provider menu is skipped. The immutable runtime image and model are the values declared by the profile, and the provenance block prints in the summary.

Analysis

resolveOnboardOptions resolves --profile into a ServingProfileProvenance, and applyServingProfileEnvironment exports it for the run:

env[NEMOCLAW_SERVING_PRESET_ENV] = options.servingProfile;

The preset tells provider selection which profile to serve after a local inference provider is chosen; it does not choose the provider. Nothing else in this flow consumed the provenance, so provider selection behaved as if no profile had been requested and presented the menu.

The two inputs were tested independently on the DGX Spark host. The preset alone reproduced the menu. Adding the provider required by the profile skipped it:

NEMOCLAW_SERVING_PRESET=<profile>                                  -> menu shown
NEMOCLAW_SERVING_PRESET=<profile> NEMOCLAW_PROVIDER=install-vllm -> menu skipped

The flag was unusable rather than inconvenient: PROFILE_CONFLICT_ENV rejects an operator-supplied NEMOCLAW_PROVIDER together with --profile, so the missing provider could not be supplied separately. Without a TTY, the run blocked on the hidden prompt, matching the report.

Fix

Derive the provider from the profile's backend and export it for the same run:

export function servingProfileProviderKey(provenance: ServingProfileProvenance): string | null {
  switch (provenance.recipe.backend) {
    case "vllm":
      return "install-vllm";
    case "install-llama-cpp":
      return "install-llama-cpp";
    default:
      return null;
  }
}

applyServingProfileEnvironment sets NEMOCLAW_PROVIDER next to the preset and restores both afterward. validateServingProfileConflicts has already rejected an operator-supplied NEMOCLAW_PROVIDER, so the run does not overwrite operator state.

The mapping is applied to explicit, installer, and resume paths. A backend with no configured provider now fails before onboarding changes runtime resources:

Serving profile '<id>' uses backend '<backend>', which onboarding cannot configure.

Tests cover both supported provider mappings, all three profile paths, run-scoped cleanup after success and handled failure, cleanup after an invalid agent manifest, and the unsupported-backend result.

Changes

• src/lib/onboard/command.ts: map a profile backend to its inference provider, export it with the preset for the run, and reject a backend with no provider.
• src/lib/onboard/command.test.ts: cover both mappings, every profile path, unsupported backends, and provider cleanup.
• docs/inference/set-up-vllm.mdx: document provider selection and the unsupported-backend boundary for --profile.

Platform Scope

The issue was reproduced and the change was verified on our DGX Spark aarch64 test host, matching the reporter's platform. The change is provider and flag resolution with no platform-specific branch, so it applies wherever a compatible profile is selected.

The test host initially had a mock vLLM process listening on localhost:8000, which caused the first run to reuse the running instance. Stopping it produced the managed-install run quoted above. Both runs skipped the provider menu.

📝 Walkthrough

Walkthrough

Serving profiles now resolve to supported onboarding providers. Onboarding rejects profiles without a provider mapping and temporarily scopes NEMOCLAW_PROVIDER and serving preset variables. Tests cover provider selection, unsupported backends, and environment restoration.

Changes

Serving profile provider flow

Layer / File(s)	Summary
Provider mapping and profile resolution src/lib/onboard/command.ts, src/lib/onboard/command.test.ts, docs/inference/set-up-vllm.mdx	servingProfileProviderKey maps vLLM and llama.cpp backends to provider keys. Profile resolution rejects unsupported backend/provider combinations and skips the provider menu for mapped profiles. Tests cover explicit and resumed onboarding paths.
Scoped provider environment src/lib/onboard/command.ts, src/lib/onboard/command.test.ts	Onboarding sets NEMOCLAW_PROVIDER with the serving preset and restores both variables after completion or handled errors. Tests cover unset, blank, and invalid-manifest cases.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to 08a49

The change makes --profile select its required provider so onboarding applies the requested serving profile instead of opening the provider menu; no actionable merge-blocking risk remains after normal checks and review.

Security Code Review

Verdict

PASS. I reviewed the complete change at 08a49f80b. It restores the existing --profile contract by selecting only a catalog-supported inference provider, rejects unsupported backends before runtime changes, and restores temporary environment state after success and handled failure. I found no security findings.

Findings

None.

Detailed Analysis

1. Secrets and Credentials — PASS. The change does not read, store, print, or forward credentials. It changes only the provider and serving-profile environment values.
2. Input Validation and Data Sanitization — PASS. The provider comes from an exact mapping of catalog-derived backends. Unknown backends fail before onboarding runs, and existing conflict validation rejects an operator-supplied provider with --profile.
3. Authentication and Authorization — PASS. No authentication, authorization, identity, or access-control behavior changes.
4. Dependencies and Third-Party Libraries — PASS. No dependency, package, image, or third-party code changes.
5. Error Handling and Logging — PASS. Unsupported backends produce a bounded message containing only the profile ID and backend. Temporary provider state is restored after handled errors, including previously unset and blank states.
6. Cryptography and Data Protection — PASS. No cryptographic, transport-security, or protected-data behavior changes.
7. Configuration and Security Headers — PASS. The provider value is selected from two exact internal values, remains scoped to one onboarding run, and does not change network policy or security headers.
8. Security Testing — PASS. Tests cover both supported mappings, explicit/installer/resume paths, unsupported backends, successful cleanup, handled-error cleanup, and invalid agent-manifest cleanup. The focused suite passed 59/59, and repository hooks passed.
9. System Security — PASS. The change adds no shell execution, filesystem permission changes, network access, container privileges, or runtime resource mutation. An unsupported backend stops before runtime resource changes.

[prekshivyas]

The selected serving profile now supplies the provider implied by its backend for explicit, installer, and resume paths, and unsupported backends fail before runtime mutation. Scoped environment restoration is covered for success and handled-error paths, and the documentation matches the CLI behavior.

Cross-issue sweep: no additional candidate issues found.
